Figure 5. — Rio et al.'s [8] experiment 2. (a) Schematic of virtual crowd (12 neighbours). A subset of neighbours (0–12) was perturbed, predominantly in the near or the far row. (b) Results for heading perturbation: mean final heading as a function of the number of perturbed neighbours, for each row (curves). (c) Results for speed perturbation: mean final speed as a function of same. Solid curves represent human data, dotted curves the visual model and dashed curves the omniscient model. Shaded regions represent 95% confidence intervals for the human data. (Modified from [8], with permission.) (Online version in colour.)
